Air quality and emissions monitoring with organized records
Link sampling, field conditions, methods and results to the references selected and maintained by the lab.
For teams that monitor air and emissions
Teams that measure emissions from stationary sources and assess ambient air and indoor air in air-conditioned spaces, with reports the client uses for licensing and environmental management.
Stationary sources
Stack sampling of particulate matter and gases, with the sampling conditions recorded alongside the sample.
Black smoke
Ringelmann scale readings recorded with date, time, conditions and a photo of the point, in a field form set up by the lab.
Ambient air
Monitoring points with results compared with the standards the lab registers, such as those in CONAMA Resolution 506/2024.
Indoor air
Air-conditioned spaces assessed against the reference values the lab registers, such as those in ABNT NBR 17037:2023.
Field conditions recorded alongside the sample
On the stack platform, the technician records the point, conditions and photos in the sampling app. Offline mode covers the operations confirmed in testing on the device, and data is sent when the connection is back.
- Configurable field forms, for example for isokinetic sampling or the Ringelmann scale
- Photos, GPS and sampling time
- Data sent when the connection is back
References by type of assessment
Sampling methods, emission limits and air quality standards come from different sources. The lab selects and registers the reference for each case, and the system compares the result with it.
Sampling methods
Sampling at stationary sources and in ambient air follows the methods the lab adopts and validates. The system records the method and the sampling conditions. Method calculations come from the instrument or the lab's spreadsheet, by file import.
Emission limits for stationary sources
CONAMA Resolution 382/2006 applies to sources whose installation licence was requested after 02/01/2007, and CONAMA 436/2011 to sources from before that date. The environmental licence may set stricter limits, which the lab also registers.
Ambient air quality standards
National standards are set in CONAMA Resolution 506/2024, with interim standards PI-2 in force since 01/01/2025. The standards in CONAMA 491/2018 were revoked by 506/2024; its Annex III attention, alert and emergency levels for critical episodes remain.
Indoor air in air-conditioned spaces
Anvisa RE 9/2003 was revoked by Anvisa RDC 886/2024. Law 13,589/2018 (PMOC) still cites the revoked RE 9/2003 and ABNT technical standards. ABNT NBR 17037:2023 sets reference standards. Applying it to each case requires a technical and regulatory assessment: check with the client and the health surveillance authority which reference to adopt.
Limits registered and validated by the lab
Limits and their updates are maintained by the laboratory. The system compares the result with the reference registered for each type of assessment and does not update standards on its own.
Technical decisions, such as acceptance criteria, decision rules, method validation and release of results, belong to the laboratory. The system records and organizes these decisions.

Field forms built by the lab
The lab builds the field forms, for example for isokinetic sampling or Ringelmann scale readings. The technician fills them in on the app, and the record stays linked to the sample, with a history of what was filled in.
See this flow in the demoHow the system supports monitoring
From field sheet to report, with each reference stated in the record.
Comparison with the reference for the case
When results are entered, each parameter is compared with the reference registered for that source or point, and anything outside is flagged for review.
Analyzer and spreadsheet results by file
Instrument results come in by file (CSV, TXT, XLS, XLSX, ASTM, HL7, XML, JSON or fixed-width text), through a local agent that watches a folder, by manual upload or by webhook. Each instrument is configured and tested with the laboratory.
Sources and points identified
Each sample stays linked to its source or point of origin, with a history of who did what and when.
Recurring campaigns
Sampling plans with a calendar and frequency generate the work orders for monitoring campaigns.
Report in the lab's template
Configurable templates, technical review before issue and revisions of reports archived with reason and person responsible.
Export for reporting
The system does not send data to the environmental agency. Results can be exported as XLSX, CSV or PDF so the team can prepare the report.
Modules available according to the contracted scope.
Each result compared with the reference registered for the source or point
Stacks, black smoke, ambient air and indoor air follow different references. The lab registers each one, the system compares, and the technical manager reviews and signs the report.
- Reference stated in the record of each assessment
- Values outside the criterion flagged during review
- Report in the template set up by the lab
Features mentioned on this page
Each feature is shown with its current status and with what remains the lab's responsibility.
| Topic | Status | What exists today | Limit / laboratory responsibility |
|---|---|---|---|
| Regulations and limits | Depends on configuration | The laboratory registers regulations, matrices and maximum allowed values, and the system compares each result with the limits registered for the service. | Regulations are not preloaded. Registering, checking and updating limits are the laboratory's responsibility. |
| Sampling | Partial | Sampling schedules with calendar and frequency that create work orders automatically, plus field sampling records in the app. | There is no statistical sampling plan, such as ISO 2859 or AQL. The sampling method and plan are defined by the laboratory. |
| Sampling app with offline mode | Available | The app downloads sampling jobs, including PDFs, for work without internet. It records photos, the client's signature, GPS and checklist, and sends them in batches, with retries, when the connection returns. | Offline mode covers the operations confirmed in on-device testing. Validate your sampling flow in airplane mode during implementation. |
| Instrument result import | Via file import | Imports results from CSV, TXT, XLS and XLSX files and from ASTM E1394, HL7 v2, XML, JSON and fixed-width text formats. Files arrive through an agent installed at the laboratory that watches a folder, by manual upload or by webhook. | The system does not connect to the serial port or directly to the instrument. The ready-made import profiles are generic, with no reader specific to a manufacturer or model, and each instrument is configured and tested with the laboratory. |
| Continuous serial capture | Requires case assessment | The current version does not read instruments through the serial port or through a direct real-time connection. Results come in by file, sent by the local agent, manually or by webhook. | Continuous serial capture is not available in the current version. The needs of each instrument are assessed case by case during the initial assessment. |
| Reporting of results | Available | Reports in configurable templates, with comparison against registered limits, marking of accredited tests, partial reports and revisions archived with reason and owner. | Report content, the decision rule and statements of conformity are defined and checked by the laboratory. The uncertainty shown on the report is the value entered, since the system does not calculate it. |

Frequently asked questions
Does the system ship with emission limits and air quality standards?
No. The lab registers the limits and standards it uses, such as those in CONAMA 382/2006, 436/2011 and 506/2024, and keeps them up to date. During implementation, our team helps build these records.
Does Anvisa RE 9/2003 still apply to indoor air?
RE 9/2003 was revoked in 2024 by Anvisa RDC 886/2024. Law 13,589/2018, on HVAC maintenance plans (PMOC), still cites RE 9/2003 and ABNT technical standards. Check with the client and the health surveillance authority which reference to adopt, such as ABNT NBR 17037:2023.
What about CONAMA 491/2018?
The air quality standards in CONAMA 491/2018 were revoked by CONAMA 506/2024. The articles and Annex III on critical air pollution episodes remain in 491/2018.
Does the system calculate isokinetic sampling?
No. The system records the sampling conditions filled in on site and receives, by file import, the result from the instrument or the lab's calculation spreadsheet. Validating those calculations is the lab's responsibility.
Is there a ready-made form for Ringelmann or isokinetic sampling?
The lab builds the field forms in the system, with the fields its method requires. There is no specific ready-made form for each method.
Does the system send results to the environmental agency?
No. Results can be exported as a spreadsheet or PDF so the team can prepare the report. Submission is done by the lab or by the client.
Does sampling work without internet?
The app downloads the sampling jobs for offline work and sends the data when the connection is back. Offline mode covers the operations confirmed in testing on the device. Validate your sampling workflow in airplane mode during implementation.
